Contest: It's "Halloweek" on mental_floss!

Halloween is my very favorite holiday -- and yes, I'll admit to getting into it super-sexy-costume style. (I once dressed up in a red miniskirt, a t-shirt with my name on it, lots of fake blood, and a celery stick in my hair -- voila, "Bloody Mary.") We'll be celebrating on the blog from now right up until the big day. So for this week's contest, your mission is clear: Send us your ghouliest, creepiest, crawliest, coolest, or otherwise awesome-est costume ideas from Halloweens past or present. Three rules:

1. No store-boughts -- we like our ingenuity homemade. Store-bought components are okay, of course, but no showing up as Superman unless you made your cape out of a garbage bag and some red paint.
2. Pictures will help. Also, even if you don't win, we'll have a Halloween parade on the day itself, and you'll be included. (You can email them to us at tips-at-mentalfloss.com.)

3. The deadline is, as ever, Sunday night at the witching hour (Eastern). But we'll be accepting parade entries right up until Monday night at the same eerie time.
